Maybe you can't get arrested to frequently or else you completly lose the game. This 1 hour thing is interesting. It may be due to heavier traffic, or even more crowded streets; you might have to slow down your running because there are so many people or you might have to wait at the crosswalks if you don't want to get run over or get arrested for jaywalking

Weather effects more than graphics? Imagine if it's storming and it makes the streets wet and Niko has to try real hard not to slip when he's running? Imagine having to CHASE someone in such weather on foot, much less in car? Oh man.
